Game kinda sucks. It's way too freaking hard with the mashers. And losing a level for touching the slime chest is the most unfair bullshit I have ever heard of. Combine that with a thousand game overs and I honestly hate this game.
Normally I welcome criticism, but looking at your comment history I can see you're not really interested in anything constructive, which is too bad. The game certainly has flaws, some of which will be fixed, others of which will at least be learned from for future games. There's no reason for the attitude though. It's possible to discuss flaws without being rude (as most of the comments below demonstrate).
